This week it’s all about the Dodge Viper with it’s record lap at Laguna Seca and rumoured Ferrari involvement. But no matter how much current interest there is in the Viper the 2010 model year marks the last run of the 600-hp beast. So to keep sales and consumer interest high for the next 12 months, Dodge is adding new colors, enhancing performance and releasing several limited-edition models.

Standard Viper SRT10 models receive two new exterior colors – Toxic Orange Pearl Coat and Bright Silver Metallic Clear Coat. Performance tweaks include a new shorter fifth gear ratio (changing from .74 to .80) this improves high speed acceleration with the 0-200 mph run dropping by 14 seconds. The track-ready ACR models get a new short-throw shifter, and some aerodynamic tweaking to the rear wing to lower drag while improving downforce.

From today, the automaker has announced the first two special editions of the Viper, and more are set to come.

The Dodge Viper ACR 1:33 Edition, pays tribute to the recent record-setting run at Laguna Seca, it’s easily identified by its unique two-tone Black Clear Coat/Red Clear Coat exterior color (the opposite of the original Viper ACR color). Other cosmetic enhancements include piano black console plastics with red gauge highlights and red stitching in the interior.

The Vooodoo-edition Viper ACR gets an all Black Clear Coat exterior with a Graphite stripe outlined in red. It’s highly exclusive with only 10 cars being produced with the unique striping on both the exterior and steering wheel.
